FIELD OF THE INVENTION

[0002] The present invention relates to laundry detergent compositions comprising one or more hydrophobically modified polyamines that provide enhanced hydrophilic soil, inter alia, clay, removal benefits. The present invention also relates to methods for removing hydrophilic soil form wearing apparel.

BACKGROUND

[0003] Fabric, especially clothing, can become soiled with a variety of foreign substances ranging from hydrophobic stains (grease, oil) to hydrophilic stains (clay). The level of cleaning that is necessary to remove said foreign substances depends to a large degree upon the amount of stain present and the degree to which the foreign substance has contacted the fabric fibers. Grass stains usually involve direct abrasive contact with vegetative matter thereby producing highly penetrating stains. Clay soil stains, although in some instances contacting the fabric fibers with less force, nevertheless provide a different type of soil removal problem due to the high degree of charge associated with the clay itself. This high surface charge density may act to repel some laundry adjunct ingredients, inter alia, clay dispersants, thereby resisting any appreciable peptization and dispersal of the clay into the laundry liquor.

[0004] A surfactant per se is not all that is necessary to remove unwanted clay soils and stains. In fact, most surfactants by themselves in water are surprisingly poor at removing clay soils from fabric. Not all surfactants work equally well on all types of stains. In addition to surfactants, polyamine-based hydrophilic soil dispersants are added to laundry detergent compositions to “carry away” clay soils from the fabric surface and to stabilize the removed particles in solution sufficiently to minimize the possibility that the clay soil will be re-deposited upon the fabric. However, unless the clay can be initially removed from the soiled fabric, especially in the case of hydrophilic fibers, inter alia, cotton, there will be nothing in solution for the dispersants to bind to and keep suspended.

[0005] It has been known to include hydrophobically modified polyamines in detergent composition, however it has been surprisingly found that a hydrophobically modified polyamine having non-homogeneous quaternization and/or partial quaternization demonstrates a higher efficacy than known hydrophobically modified polyamine structures.

[0006] Additionally it has been surprisingly found that when non-homogeneous quaternization and/or partial quaternization is combined with 50% or less by moiety of an anionic capping unit, higher efficacy is demonstrated than known hydrophobically modified polyamine structures.

The term “chemical reaction products” refers to the admixture obtained by a process wherein substantially linear alkyl units are the desired product but nevertheless some non-branched alkyl units are formed. When this definition is taken together with preferably one of R, R¹, and R² in formulae (XII) and (XIII) is methyl and the other units are hydrogen, the preferred mid-chain branched alkyl sulfate and alkyl alkoxy sulfate surfactants comprise one methyl branch, preferably said methyl branch is not on the α, β, or the second to the last carbon atom.

Some tertiary carbon atoms may be present in the alkyl chain, however, this embodiment is not desired.

[0141] The integer x in formula (XIX) is from 0 to 13. The integer y in formula (XIX) is from 0 to 13. The integer z in formula (XIX) is either 0 or 1, preferably 0.

[0142] R² in formula (XVIII) is hydrogen, C₁-C₃ alkyl, and mixtures thereof. Preferably R² in formula (XVIII) is hydrogen.

[0143] M′ in formula (XVIII) denotes a water soluble cation with sufficient charge to provide neutrality, preferably hydrogen, a water soluble cation, and mixtures thereof. Non-limiting examples of water soluble cations include sodium, potassium, lithium, ammonium, alkyl ammonium, and mixtures thereof.

[0144] In one embodiment of the present invention mid-chain branched aryl sulphonate surfactants are “substantially linear aryl” surfactants. The term “substantially linear aryl” is defined for the purposes of the present invention as “an alkyl unit which is taken together with an aryl unit wherein said alkyl unit preferably comprises one branching unit, however, a non-branched linear alkyl unit having an aryl unit bonded to the 2-carbon position as part of an admixture is included as a substantially linear aryl surfactant”. The preferred alkyl units do not have a methyl branch on the second to the last carbon atom. Typically the branched chains are a mixture of isomers. However, in the case of the mid-chained branched aryl sulphonates of the present invention, the relative position of the aryl moiety is key to the functionality of the surfactant. Preferably the aryl moiety is attached to the second carbon atom in the branched chain as illustrated herein below.

[0145] In one or more embodiments mid-chain branched aryl sulphonates of the present invention will comprise a mixture of branched chains. Preferably R¹ in formula (XIX) is methyl, the index z in formula (XIX) is equal to 0, and the sulphate moiety is para (1,4) to the branched alkyl substituent thereby resulting in a “2-phenyl aryl sulphonate” defined herein by the general formula (XX):

[0146] wherein x and y in formula (XX) are the same as described in formula (XIX).

[0147] Typically 2-phenyl aryl sulphonates are formed as a mixture together with “3-phenyl aryl sulphonates” defined herein by the general formula (XXI):

[0148] wherein x and y in formula (XXI) are the same as described in formula (XIX).

[0149] The surfactant properties of the mid-chain branched aryl sulphonates of the present invention can be modified by varying the ratio of 2-phenyl to 3-phenyl isomers in the final surfactant mixture. A convenient means for describing the relative amounts of isomers present is the “⅔ phenyl index” defined herein as “100 times the quotient of the amount of 2-phenyl isomer present divided by the amount of the 3-phenyl isomer which is present”. Any convenient means, NMR, inter alia, can be used to determine the relative amounts of isomers present.

EXAMPLE 1

[0209] Hydrophobically Modified Polyamine Derived from Bis(Hexamethylene)-triamine Containing 100 Moles of Ethylene Oxide (20 per NH), Average of Two Benzyl Groups, and Average of One Sulfate Group Per Molecule.

[0210] a) Ethoxylation of Bis(hexamethylene)triamine to average of 20 Ethylene oxide units per NH—The ethoxylation is conducted in a 2 gallon stirred stainless steel autoclave equipped for temperature measurement and control, pressure measurement, vacuum and inert gas purging, sampling, and for introduction of ethylene oxide as a liquid. A approximately 9.07 kg (20 lb.) net cylinder of ethylene oxide (ARC) is set up to deliver ethylene oxide as a liquid by a pump to the autoclave with the cylinder placed on a scale so that the weight change of the cylinder can be monitored.

[0211] A 362 g portion of Bis(hexamethylene)triamine (BHMT) (m.w. 215, 1.68 moles, 5.04 moles nitrogen, 8.4 moles ethoxylatable (NH) sites), is added to the autoclave. The autoclave is then sealed and purged of air (by applying vacuum to minus 94.8 Mpa (minus 28 inches Hg) followed by pressurization with nitrogen to 1.62 MPa (250 psia), then venting to atmospheric pressure). The autoclave contents are heated to 80° C. while applying vacuum. After about one hour, the autoclave is charged with nitrogen to about 1.62 MPa (250 psia) while cooling the autoclave to about 105° C. Ethylene oxide is then added to the autoclave incrementally over time while closely monitoring the autoclave pressure, temperature, and ethylene oxide flow rate. The ethylene oxide pump is turned off and cooling is applied to limit any temperature increase resulting from any reaction exotherm. The temperature is maintained between 100° C. and 110° C. while the total pressure is allowed to gradually increase during the course of the reaction. After a total of 370 grams of ethylene oxide (8.4 moles) has been charged to the autoclave, the temperature is increased to 110° C. and the autoclave is allowed to stir for an additional 2 hours. At this point, vacuum is applied to remove any residual unreacted ethylene oxide.

[0212] Next, vacuum is continuously applied while the autoclave is cooled to about 50° C. while introducing 181.5 g of a 25% sodium methoxide in methanol solution (0.84 moles, to achieve a 10% catalyst loading based upon ethoxylatable sites functions). The methanol is removed from the autoclave under vacuum and then the autoclave temperature controller setpoint is increased to 100° C. A device is used to monitor the power consumed by the agitator. The agitator power is monitored along with the temperature and pressure. Agitator power and temperature values gradually increase as methanol is removed from the autoclave and the viscosity of the mixture increases and stabilizes in about 1.5 hours indicating that most of the methanol has been removed. The mixture is further heated and agitated under vacuum for an additional 30 minutes.

[0213] Vacuum is removed and the autoclave is cooled to 105° C. while it is being charged with nitrogen to 1.62 MPa (250 psia) and then vented to ambient pressure. The autoclave is charged to 1.28 MPa (200 psia) with nitrogen. Ethylene oxide is again added to the autoclave incrementally as before while closely monitoring the autoclave pressure, temperature, and ethylene oxide flow rate while maintaining the temperature between 100° C. and 110° C. and limiting any temperature increases due to reaction exotherm. After the addition of 4180 g of ethylene oxide (95 mol, resulting in a total of 20 moles of ethylene oxide per mole of ethoxylatable sites on BHMT), the temperature is increased to 110° C. and the mixture stirred for an additional 2 hours.

[0214] The reaction mixture is then collected into a 22 L three neck round bottomed flask purged with nitrogen. The strong alkali catalyst is neutralized by slow addition of 80.7 g methanesulfonic acid (0.84 moles) with heating (100° C.) and mechanical stirring. The reaction mixture is then removed of residual ethylene oxide and deodorized by sparging an inert gas (argon or nitrogen) into the mixture through a gas dispersion frit while agitating and heating the mixture to 120° C. for 1 hour. The final reaction product is cooled slightly and stored in a glass container purged with nitrogen.

[0215] b. Quaternization of BHMT E20 with 2 equivalents of benzyl bromide (3 mol N per mol polymer)—Into a weighed, 1000 ml, 3 neck round bottom flask fitted with argon inlet, condenser, addition funnel, thermometer, mechanical stirring and argon outlet (connected to a bubbler) is added BHMT E020 (522.8g, 0.111 mol polymer, 0.333 mol N, 98% active, m.w.−4615) under argon. The material is heated to 80° C. with stirring until melted. Next, benzyl bromide (37.6g, 0.220 mol, m.w. 171.04) is slowly added to the melted BHMT E020 using an addition funnel over a period of 10 minutes. The reaction is complete after stirring at 80° C. for 6 hours. By NMR, the amine groups are 64% quated (i.e., approximately 2 out of 3 nitrogens on average are quated)

[0216] c. Sulfation (1 equivalent) of BHMT E20 dibenzyl monomethyl quaternary ammonium salt—Under argon, the reaction mixture from the quaternization step is dissolved in 1 L of methylene chloride and is cooled to 5° C. to 10° C. using an ice bath (BHMT E20, 90+mol % quat, 0.111 mole, 0.555 mol OH). Chlorosulfonic acid (12.9 g, 0.111 mol, 99%, mw-116.52) is slowly added using an addition funnel at such a rate the temperature of the reaction mixture does not exceed 10° C. The ice bath is removed and the reaction is allowed to rise to room temperature (23° C.). After 6 hours the reaction is complete. The reaction is again cooled to 5° C. to 10° C. and sodium methoxide (48 g, 0.222 mol, 25% in methanol, m.w. 54.02) is slowly added to the rapidly stirred mixture. The temperature of the reaction mixture is not allowed to rise above 10° C. The reaction mixture is transferred to a single neck round bottom flask. Purified water (1300 ml) is added to the reaction mixture and the methylene chloride, methanol and some water is stripped off on a rotary evaporator at 50° C. The clear, light yellow solution (About 30-40% hydrophobically modified polyamine in water) is transferred to a bottle for storage. The final product pH is checked and adjusted to approximately 8 to 9 using 1N NaOH or 1N HCl as needed. By NMR, 19% of the terminal hydroxyl groups of the ethoxylate chains are sulfated.

With good mixing, dimethyl sulfate (14.2 g, 0.113 mol, 99+%, mw 126.1) is dripped in from an addition funnel at such a rate the temperature of the reaction mixture does not exceed 10° C. The ice bath is removed and the reaction is allowed to mix at room temperature (23° C.) for 2-3 hours at which point the reaction is complete. By NMR, the amine groups are 90% quaternized.

[0219] b. 90+% Sulfation of 2a—Under argon, the reaction mixture from the quaternization step, 2a, is dissolved in 1 L of methylene chloride and is cooled to 5° C. to 10° C. using an ice bath (BHMT E20, 90+mol % quat, 0.555 mol OH).
